Oops, wrong sister.....

I've been having fun singing Christmas carols around the house, and Madelynn loves trying to learn the words to them.  The other day she requests I sing that song about her sister. I ask, "what song is that?"

"You know, it goes Annabelle to the world..."

"Wha?......Oh! Do you mean Joy to the world?"

"Oh yes, Joy to the world"
